Video Pick: Blowing Bubble Nets

Humpbacks are the only whales known to blow bubble nets -- a circle of bubbles that traps schools of fish for easy capture. Although this hunting technique has been documented in humpbacks for decades, just how whales make the nets wasn't well-understood until now, says David Wiley, a biologist with NOAA. Wiley and colleagues attached digital tags to Humpbacks' backs to find out what they do underwater when they're bubble-netting.
